IMPROVEMENT IN .WHI'IiEWASHILNG-MACHINES.v

Specification forming part of Letters Patent No. 172.067, dated January11, 1876; application tiled October 11, 1875.

To all whom 'it may concern:

Be it known that I, WILLIAM H. ALEXAN- DER, of Sharon, Norfolk county,Massachusetts, have invented certain Improvements in Machines forWhitewashing, of which the following is a specification:

This invention relates to means for laying on Whitewash, or othercoloring matters, on ceilings in a rapid and effective manner; andconsists in the following elements: first, a box or vessel forcontaining the coloring fluid; second, of a rotary brush journaledWithin the box centrally, and wallowing in the coloring fluid, and whosepurpose is to take up and deliver such coloring fluid upon the ceiling;and, thirdly, of two rigidly-disposed or stationary brushes arranged inthe upper part of the vessel above the coloring fluid, and upon eachside of the rotary brush, the purpose of the latter brushes being todistribute the coloring fluid or whitewash in a uniformly-even surfaceor coat.

The box or vessel is provided with frictionrollers, and the rotary brushwith gears for rotating it, substantially as hereinafter explained. A

The drawings accompanying this specification represent, in Figure l, aside elevation, and in Fig. 2 a vertical section, of a machine embodyingmy improvements. Fig. 3 is a section of one'of the bearings ofthe rotarybrush and its driving-gear.

In these drawings, A represents a box or Vessel, of a suitable size andshape to carry out the purpose intended-that is, of containing aquant-ity ofwhitewash or other coloring pigment or paint-being, in thisinstance, rectangular in horizontal section, and concave longitudinallyat the bottom. Centrally and transversely of the box A I dispose withinit a cylindrical brush, B, through the body C of which I pass a squareshaft, D, one end of such shaft finding a bearing in one side of the boxA, and the other end passing through the opposite side of the box, andhaving mounted upon it a spur-gear, F, which meshes into and receivesmotion from a second spur-gear, G, pivoted to the side of the box, asshown at H, this latter gear being au intermediate, and meshing into adriving-pinion, I which is pivoted to a stud,

a, projecting from the side of the said box A, a trundle-wheel, J, beingsecured to the outer end of such pinion. K in the drawing represents asecond trundlewhee1, which is acounterpart of the wheel J, and pivotedto the opposite corner of the same side of the box, while L L representtwo twin trundle-wheels pivoted to opposite upper corners of theopposite side of the box. The wheels J K L L trundle along the ceilingwhen the machine is in use,

and the former, through the agency of the pinion l and gears F and G,imparts rotary motion to the brush B, which wallows in the iiuidvcontained within the box.

In order to permit of' immediate and ready removal of the brush B, Iinclose its outer journal b within the two arms C C of an expansiblelatch, d, which is pivoted to the side of the box above such shaft, anddisposed between such box and the gear F, the two arms c c straddlin gthe journal b, and bearing against the shoulder c of the latter.

N N in the drawings represent two upright stationary brushes, extendingacross the interior of the box A, and supported upon bars O O, thesebrushes being arranged upon 0pposite sides of the central rotary brush,and raised above the fluid in the box. The upper surfaces of the threebrushes B N N are practically on a level, and are elevated slightlyabove the upper edges of the box, and slightly above the upper edges ofthe wheels J K L L.

A socket, f, is to be secured to the under side of the box A, in which astai is to be inserted, and thus provided the box is to be trundledalong the ceiling which is to be Whitend or colored, it beingpresupposed that a proper quantity of fluid is rst placed in such box.As the box is trundled along, the brush B rotates and takes up anddelivers upon the ceiling a continuous supply of coloring Huid, whilethe brushMN, which may at the time be in rear of it, distributes or laysthe iiuid thus delivered in a uniformly-even and perfect coat.

By means of my machine the whitewashing or coloring of' a ceiling may beperformed in a. fraction of the time requisite to do the same labor byhand-brushes; but, in addition to this, a great advantage attaches tothe machine, in that no iluid is spilled or spattered upon dthe Walls orfloor of the apartment, and a very even and perfect surface of coloring'or whitening is deposited.

I elaim- 1. -A machine for Whitening or coloring ceilings, composedofthe box or vessel A, brushes B N N, and wheels J K L L, the brush Bbeing mounted Within the. box, and positively rotated, substantially asherein explained, and the Whole being' essentially as and for purposesstated.

2'.V The brush VB, in combination with the trough A and expansble latehd, substantially as shown and set forth.

In a whiteWashing-machine, the combination, with the trough and rotarydeliveringbrush, of the gearsF H, pinion Land Wheel J.

4. In a Whitewashing-machi'ne, the combination of a liquid-receptacle,friction-Wheels, and a delivery-brush, arranged in the said receptacle,and 'positively rotated 'oy power derived from the movingfriction-Wheels, as herein shown and set forth.
